    I am building a 235 Chevy and i have acquired a three deuces set up on a 4brl adapter. Can i run this on a near stock 235 or will it be to much for it to handle? The carbs are three Rochester 2gc. I will be running a Clifford intake and split headers.

    You can't build a 235 that could use all that carburetor! Heck 2 1bbl's is about the max for a streetable 235.

    These are all triple carbureted Chevy 230 or 235 inlines and none has a fuel richness problem. It has been done on 216 and up for decades. I know of 261'a and 250's up with five carburetors and all run very well.

    What if i bought a 2x1 intake and adapters to run the two Rochesters on it? These are the bigger 4bolt type carbs instead of the 2 or 3 bolt ones.

    All those examples are 1 barrel carbs and small ones at that. He's talking about 3 two barrel carbs with MUCH higher CFM. One Rochester 2G would be enough to make a 261 happy and 3 would be hopeless.

    X2 on a stock 235 not needing more than one 2GC.

    FWIW, There are lots of guys appearing to be running lots of carbs, but sometimes there's only one or two really p***in' gas. At a recent GoodGuys show a 6-71 blower with six 97's was really an empty case covering a stock 4bbl under there.
